To all whom'z't may concern:

Be it "known that I, ZERAH' G. HAYDEN, a

citizen of "the United States, residing'at Eldora, in the county ofHardin and State 7 same.

The primary object of this inventionis the provision ofa novel .formofladder designed to be associatedwith a standard, in the-nature of a postor pole or mastyor with a building structure, so as to admit of theascent ofa person'to'the top of a standard or structure being effectedin, a convenient, safe and expeditious manner; also to admit of thedescent of the person-from the top of the pole being effected inl asimilar manner. Y

Another object of the invention is the 'pro vision of a device of thischaracter that will be of simple and durable construction,'can bereadily mounted in operative position, and which includes a .series ofsteps or rungs which can be conveniently adjusted so as to be set atvarious distances apart.

Other object swill appear and be better understood from that embodimentof my invention of which the following is a specification, referencebeing had to the accompanying drawings forming a part'thereof, in which:i 5

Figure "1 is aside elevation of a fence structure, showing a fence postequipped with a ladder constructed in accordance with my invention. Fig.2 is a detail perspective view ofthe upper end of one ofthe laddersections, showing the same detached from operative position, and showingthe manner of connecting one of the steps or rungsthereto,

Fig. 3 is a section taken on the line 33 of Fig. 1,

Fig. 4 is a perspective view of a modified form of step or rung, and

Fig. 5 is a detail perspective view of an- T other modified form of stepor rung.

Referring to the drawings in detail, the letter A designates a fencestructure and B a fence post.- Associated with the post B is a ladderformed of a pair of sections mounted, respectively, on opposite sides ofthe post, as shown in Fig.- 1-. Each section includes Specification ofIletters r am.

a standard 1, whichengages along the adjaj cent side of the post and hasits upper end bent lJOPIOVlClG afian'ge 2, which overlies the upper endof the post and is secured thereto in any suitable manner. Each standard1 is provided at spaced points throughout its length with outwardlyoffset portions '3, and each offset portion-3 has stamped therefrom apair ofinwardly extending tongues 4, which are of L-shape inconfiguration." Mounted on" each of the standards 1 is a pluralityof'steps, or rungs, designated 5, Each of the steps or {rungs'5 is ofL-shape, having a vertical portion 6 and a horizontal portion 7.- Thehorizontal portion 7 of each step or rung 5 is provided,

adjacent the point of juncture between the vertical portiontl and'thehorizontal portion 7, with a slot 8 for the passage of the adj acentstandard 1, and the vertical portions 6 of the stepsor rungs 5 lie,asshown in Figs.

1, 2 and 3, at the rear or inner side of the adjacent standard 1. Thevertical-portion 6 of each step or rung is provided with a cutoutportion to provide an opening 9, through which projects one of thetongues 4, and the upper. wall of the opening 9 is provided with arecess '10, which receivesthe horizontal 1 portion of the adjacent Lshapedtongue 4, as shown in Fig. 3. The slot 8 in the horizontal'portion7 of each step or rung 5 communicate s'with' a recess '11 formed in theloweredge of the part of the adjacent vertical portion 6, and thesaidrecess 11 receives the horizontal portion of another of-the Lshapedtongues 4, asshown in Fig. 2.' The tongues t effectively support thesteps or rungs 5 on the standards'l. The horizontal portions 7 of thesteps or rungs 5, illustrated in Figs. 1, 2 and 3, are

provided, adjacent their outer ends with slots 12, so as to provide hand-g' rips 13, which can be convenientlygripped by 'a'person during theact of ascending or descending the laddenf j, v p the drawings, amodified form of step or rung is illustrated, andis shown consisting ofan L-sh'aped member In Fig. 4 of having a vertical portion 15 and ahorizontal portion 16. The horizontal portion 16 is of a widthconsiderably greater than the width of the vertical portion 15 and isprovided, at points on opposite sides of the vertical portion 15, withopenings or cutout portions 17 to provide handv grips 18. The horizontalportion was also provided with an opening 19 for the passage of thestandard 1 with which the said step or rung is to be associated. Theverticalportion15 of the step or rung, illustrated in Fig. 4, isprovided with a cutout portion 20 for-the passage of one of the L-shapedtongues 4, and the upper end of the cutout portion or opening 20 isrestricted, as at 21,.to'provide a recess for the reception of thehorizontal portion of one ofthe L-shaped t ngues-when the step or rungis mounted on one of the sections. The lower end of the vertical portion15 is also provided with a recess 22 for the accommodation of another ofthe 'L- shaped tongues 4 when the step or rung is mounted on one of thesections 1. A pair of inclined brace arms 24: have connection,respectively, with the vertical sides of the vertical portion 15 of thestep, illustrated in Fig. 4, and with the horizontal portion 16 thereof,and serve to reinforce the points of connection between the verticalportion 15 and horizontal portion 16,, and also to serve asradditionalhand grips for a "person during the act of ascending or descending theladder. 4

The step or rung illustrated in Fig. .5 is

similar to those disclosed in Figs. 1, 2 and 8, having a recess 25 atthe point of connection between the vertical and horizontal portions forthe passage of the standard 1 to which the step stud is to beconnected,'and the vertical portion is provided with an opening whichhas its upperend communicating with a recess 27 for the reception of thehorizontal portion of one of the L- shaped tongues 4t, when the step ismounted on the standard, and the lower end of the vertical portion isprovided with another rebe understood that the same can be mounted atthe corner of a building, or it can be mounted on a telegraph pole, themast of a sh p, or similar standards. However, the

we P h s patent a 12 attains ta ladder is designed, particularly, to beassociated with a fence post, soas to admit of a person scalingthe fencewithout coming in contact with the panel of the fence.

As shown in Fig. 1, the post is provided, at the upper end thereof, withan extension 30, which provides a hand hold which can be gripped personupon reaching the top of the post.

It is evident that various chan es might be resortedto in theconstruction, form and arrangement of the several parts withoutdeparting from the spirit and scope of the invention. a

\Vhat I claim is:

l. A ladder of the class described comprising a pair ofsections eachconsisting of a standard having a series of tongues stamped therefrom,andv a plurality of steps of L shape in configuration and havinghorizontal portions provided with slots for thepassage of thestandards,and h i -th vertical portions provided with recesses for thereception of the tongues on the standa ds,

'2. A ladder comprising a pair of standards, a. plurality of stepsassociated with each of the standards and including a horizontal portionhaving a slot therein for passage-ofthe adjaeentstandard and a verticalportion having detachahleconnection with the standard, andhandgripsforined on the horizontal portions of-the steps.

3. A ladder including a standard, a plurality of steps associated withthe-standard and each consisting of a vertical portion for detachableconnection with the standard, and ahorizontal portion having acorrugated surface thereon, and provided with hand grips for the purposespecified. I at. A ladder including a standard, a plurality of stepsassociated with the standard and each consisting of a vertical portionand a horizontal portion carried by the Vertical portion, inclinedbracing elements having connection, respectively, with the verticalportion and the horizontal portion, and hand grips formed on thehorizontal por- .tion.
